Web App Login Issue: Showing "Successfully signed in!" but stuck on login page

When attempting to log in to the Lumi Cloud web app (app.lumi.education), the login authentication succeeds, but the application fails to redirect to the user dashboard or editor interface.

1. Enter valid account credentials (or use standard sign-in options) and click Sign in.

2. A green notification toast appears saying "Successfully signed in!".

3. The page remains stuck on the login form without redirecting to /dashboard or /projects.

4. Clearing browser cache, clearing local storage, switching browsers, switching devices including laptop and mobile and manually navigating to /dashboard after receiving the "signed in" status (still redirects back or fails to load the session).
